besides the NEW and the OLD
what are major characteristics between the old and new world monkeys….what should i know about the differences?
any other information regarding the question, is highly appreciated thank you
old world: from Africa and Asia, have narrower noses and larger bodies, spend more time on the ground, have opposable digits and some don’t have tails at all and none have prehensile tails (work as 5th limb)
new world: from Mexico, Central America, and South America, do not have fingernails or opposable digits, all have prehensile tails

Many new world monkeys have prehensile tails. This adaptation seems to have come about because the Amazon basin floods often and gripping a branch with the tail to reach fruit at dangerous tips of branches is the only alternative to traveling on the ground.
Another difference is that the nostrils on new world monkeys open more to the sides of the nose instead of downward as in old world monkeys.
